Travel this national scenic byway as it loops 66 miles along the Green Bay bluffs and through the dunes and bays of Lake Michigan. Explore lighthouses, nature preserves, and historic communities. The last few miles of the northern section of Highway 42 offer some of the most picturesque scenery, as does a hike through the 2,400-acre Newport State Park in Ellison Bay. Washington Island is a relaxing 20-minute ferry ride.
